consistent: to be, or not to be

That’s the question.

This is from a client’s point of view absent a partition.

MongoDB

Is data in MongoDB consistent?

MongoDB executes read and write operations on the primary node, and data is consistent. However, performance is limited because clients do not leverage secondary nodes. The first alternative is to execute read operations on all nodes, primary and secondary. Read performance is better, but data is no longer consistent because replication is asynchronous by default. The second alternative is synchronous replication. The data is consistent, but the performance cost is high.

Primary

Medium Read Performance, Medium Write Performance

Consistent Data

Primary + Secondary (Asynchronous)

High Read Performance, Medium Write Performance

Eventually Consistent Data

Primary + Secondary (Synchronous)

High Read Performance, Low Write Performance

Consistent Data

Data may or may not be consistent.

It’s a trade-off between consistent data and high performance. However, the enterprise can have its cake and eat it to. It doesn’t have to sacrifice consistency to maintain high performance.

Do Continuous MapReduce on Live Data?

In an effort to make Hadoop more "real-time," an entire in-memory ecosystem has sprung up around it. The pace of change in this space makes it hard to keep up. Spark is a great tool for speeding up iterative batch processing and interactive query in Hadoop. Storm is a great tool for manipulating data as it streams by. ScaleOut hServer is often placed in these categories, but while hServer can do both of these tasks, it was built with a different purpose in mind. hServer was built to let you hold your daily business data in-memory, update it as it changes, and concurrently run continuous MapReduce tasks on it to analyze it in real-time. We call this "stateful" analysis. In short, it allows you to capture perishable business opportunities using the familiar MapReduce interface-- the same interface you use for your batch analytics.

Viber has replaced MongoDB with Couchbase Server

As one of the fastest growing VoIP services in the world, the challenge at Viber, their second-generation architecture was built on top of MongoDB shards. Next, Redis was added as a cache on top of the MongoDB shards to increase throughput. Still, MongoDB was unable to meet the high throughput requirements. Finally, a second Redis cluster was added independent of the MongoDB shards. The second-generation architecture was compromised of 150 MongoDB nodes and over 100 Redis nodes.

The third-generation architecture had to support 100,000+ operations per second in the short term and 1,000,000+ operations per second in the long term. Viber chose to build their third-generation architecture on top of Couchbase Server. The third-generation architecture is compromised of 100 to 120 Couchbase Server nodes.

Viber has been able to reduce the number of database nodes required while increasing the throughput with their third-generation architecture. For example, one of their Couchbase clusters (a ten node cluster) handles 100,000 to 200,000 operations per second with over 4.5 terabytes of data.
